<P>PROBLEM TO BE SOLVED: To provide a steel frame covering structure capable of being easily constructed independent of the positional relation of steel frames in an architectural structure or the thickness of the steel frames, and preventing the generation of a thin part in expansion residue of a thermally-expansible fireproof sheet even when exposed to the heat of fire or the like. <P>SOLUTION: The steel frame covering structure includes; a steel frame with an H-shaped cross section, including two flanges facing in parallel; expanders installed at both ends of at least one of the two flanges; and the thermally-expansible fireproof sheet for covering the steel frame and the expanders. The expander includes an installation groove which can be fitted to the end part of the flange, the installation groove of the expander is fitted to the flange end part by the state of deforming a part or all of the installation groove of the expander, the expander is projected from the flange end part to the outside and installed, and the expander is deformed when heated. <P>COPYRIGHT: (C)2012,JPO&INPIT |
